Setting the Benchmark for performance Test

Question

I have a task to set a performance benchmark using stat given by google analytics.

Google Analytics stats:

My Research:-

What I did was Since daily user count is 122154 I set benchmark as follows: I set user load as 5100 since (122154/24 = 5090)

Question:- Kindly help me to verify whether my approach is correct

Answer 1

Load is rarely the same during a day. So dividing a day load by 24 to get an hour load is not realistic. Try to get more detailed load statistics from Google Analytics. Some webapplications get 90% of a days load in one hour.

Answer 2

Your calculation might not be accurate as the load might not be evenly distributed during the day, for example if your application is targeting one country there could be "dead" periods like nights or weekends and there could be "active" periods when nearly all 120 000 users are online. So you need to narrow down monitoring telemetry time frame to 24 hours, identify how does load profile look like in terms of normal and peak loads and create 2 test types:

1. Load test - simulate "normal" daily (or anticipated) load
2. Stress Test - simulate peak load. You can also try to find the breaking point by increasing the load unless response time starts exceeding acceptable threshold or errors start occurring (whatever comes the first) to measure the maximum amount of users which your system can support.
3. You can also consider Soak Testing - putting your system under a prolonged load to identify any potential memory leaks
